To all whom it 'may concern.'

Be it known that I,- ALEXANDER McDon- ALD, a subject of the' King of Great Britain, and a resident of Chicago, county of Cook, and State of Illinois,l have invented cer-` tain new and us'enl Improvements in' Grain- Shocking Machines,- of which the following is a specification.

This invention relates to shocking attachments adapted for 'use on grainbinding harf vestelfs, whereby the bundles or sheaves may be collected automatically in parallel relatien in groupsy and deposited uprightly on the ground in the forni of shocks. This application is in'part a continuation ofP my pending application Serial No. 262,599, filed November 14, 1918.

' Although various Vattennits have been made hyothers to perfect a device of this general character, I ani not aware'that anyv such attachment has everproven ysufficiently dependable or efficient to moet the general need or to go into anyex'tensive ilse.

The 'moin objects' of this invention are to 'L provide a shocker ofimproved form and 0peration', betterv adapted for siniple construcf tion and dependable C'or'ritrol; to povid shear' collector or cradle of improved con# strnction having a 4concentric-motic'wn side door and antomatic means for opening and closing said door; to provide positive perating means respectively for tilting the cradle and for sliding and opening saine,

adapted for automatic actuation and manual control; to provide transfer means for turning the sheaves vKhorizontally and dis charging same into the shocker cradle; and to provide such adevice of inexpensive de? sign and in a form adapted for ready a'ttachment to binders such as are already in use.

An illustrative embodiment` of. this in'- vention is shown in the' accompanying draw! ings, in which;`k p j n I `igfure" 1 is a vperspective front viewof the attachment in its'normal position with the cradle set ready to collect a' load vof sheaves; f.

In the embodiment 'shown in the drawings the Sheaf-collecting holder or cradle cornp'rises an end wall or head 1, a fixed wall `plate 2, and a movable wall or door plate 3. Said cradle 'secured firmly toa tiltablymounted support 4 of oblong rectangii lar shape disposed lengthwise under the lower edgeof wall 2. vSaid support' 4 includes a block 4a and has a joint device 5 to which is connected a crank rod 5a for reci rocating the cradle, as `will be further eXp ained.'t Said support 4 is sec'red rigidly to a short cross bar or Sleeve in Ithe' forni of a tube 6 which'in lturn is mounted slidzibly l'ipo'n and is concentric with'a horizontally positioned rod or'pipe 6a which extends a considerable distance from said siipport on each side. K f

The' movable plate or door 3' is operatively connected to a pair of tensionn members or cables 7 yand 7, the adjacent ends of which it will be seen, comprises substantially a hollow rusto-conoidal body. having ya closure 1 at the Vsmaller end, and includinga ypair of relatively movable side walls 2 and 3 to one of which said closure is iixed, and the top side ,being permanently open. When y themovable side 3 slides downward or back past the other side 2 the top side opening virtually enlarges on the trailing side of the cradle relative to the bodily movement of `the machir'i'e.k Y y' The construction whereby the door` 3 1s held in place for sliding back over the er terior face of wall 2 includes a pair of guide flanges la and 2 secured to the closed and open ends of the cradle respectively. j Sa-id flanges are formed with free edges projecting toward each other over the exterior face of wall 2, and the corresponding edges of door 3 fit slidably between said wall face and said free edges respectively, as shown in Fig. 3.V

Said door has a bearing strip 3b secured to its outer face a short distance upfroin its lower edge as viewed in Fig. 2, which strip slides on the upper edge of said flange 2a. A similar strip 3a is secured in like manner near the upper edge of the doorand bears upon the inwardly turned` lip l1 on the lower edge of flange l, so that the door 3 is supported and gui-ded at both ends.

In use the shocker attachment operates as follows: The cradle, resting normally as in Fig. l or with the closed end tilted downward somewhat, becomes filled with sheaves arranged with their heads toward the closed end. At the will of the operator, by means of suitable control means hereinafter de-4 scribed, the cradle is tilted (right to left in Fig. l) so as to dump the sheaves, butts down, in shock formation and at the same time theicradle stands still or substantially so for a moment while the door 3 is opening. Next, the cradle, with its door open, is drawn forward, leavingthe shock standing on the ground. rFhen simultaneously the door is restored and the cradle tilted back ready to receive another load of sheaves. Referring to Fig. l, this movement of the cradle on shaft 6 is first to the left and then to the right, but as viewed in Fig. 2, the movement is first to the right and then to the left. -4

This actionl is effected by the means next to be described. The pivotal rod 6 is journaled at 8 and D at or adjacent to its ends for oscillation on the frame part l0 to tilt the cradle. In order that the latter may be positively coturnable with said rod, the tubular shoe f5 to which the cradle is fixed is keyed slidably thereto, as by means of the spline 'll and feather l2. The franiepart 10 is secured rigidly to the vehicleframe proper or may be formed asia part thereof. Journal bearings 13 and 14 are provided for said rod 61?. .Fixed to said rod isa` crank arm 15 operatively connected for oscillatoryY actuation automatically subject to the will ofthe operator, as will be understood. See Figs. 7 and 8, 1

In order to effect automatic reciprocation of the pitman rod 5, subject to the will 0f the operator, for .positivesliding of the cradle backward and forward, thefront end of said rod is ournaled somewhat loosely at li6 to a crank arm i7, the latter being jour naled at 1,8 to frame 'l0 andbeing opera-L tively connected to cooperate withthe (tilt,-

Y stood.

111g means and being controlled preferably by the same manual clutch or equivalent means for power actuation as will be under- See Figs. 7 and S. In order to accommodate both swinging and relative twisting motion at 5, the joint is adapted for universal movement and may well be in the form of a ball and socket joint, the plate 19 being provided with a socket at 19.

The front end of cable 7 is fastened to the frame at 20 and the rearward end of cable 7lL is fastened to the frame at 2l, so that as the c 'adle moves back and forward the door plate 3 is correspondingly moved to open and restore respectively.`

1n order to transfer' the sheaves from the tying and discharge end of the binder mechanism to the upper side of the cradle, an inclined belt 22 ismounted on rolls or pulleys 23 and 24, the lower onebeing appropriately geared to the driving mechanism toeifect elevating movement, as will be understood. Guide means 25 having a 900 right-hand twist project downward from the binding mechanism for depositing the sheaves, butts outward, on the belt 22. From said belt the sheaves fall into the cradle.

Means 26 actuable by the same manual device as controls the tilt and slide of the cradle, are pivoted `to the 'frame at27 near the upper end of belt 22, to hold back the, sheaves on said belt when the cradle isd being operated for discharge. For this purpose the link 26 connects means 2G to the hand lever shown in Figs. 7 and 8.

normally engage the sheaves sufficiently to carry them upward, but the belt slides yieldingly under the sheaves when they are held back by the stop 2G. 4 i

Referring further to Figs. 7 and 8, showing the shocker controlling means somewhat diagrammatically, power is transmitted from the tread wheel 2S through shaft 29 to the reducing gears 30 and 3l and thence by V110 shaft 32 to the control clutch. Said clutch includes a pair of relatively movable plates 33 and connected to theends ofV shafts 32 and for positive coturning therewith respectively, said plates being adapted to engage each other and coact for positive mutual Ycoturning when the clutch is set. One of said plates 3a is provided with a hub projection 3G and is slidable on said rshaft 35, being splined thereto.

Said plate 34 is controlled byva toggle device including toggle bars 37 and 38 pivoted at 39 to each other and to a link 40; The opposite ends of saidbars are connected pivotally to sleeve 41 and stationary bearing 125 42 respectively. Said sleeve fits in a groove in the hub 36, so thatoperation ofthe toggle slides said plate 34into and out of engage'- ment with plate 33. The opposite end of link 40ispivoted to the short arm of a 130 Said vbelt is 100 j provided with yielding arms 22 adapted to manual control lever 43 ythe-long arm of which has a handle 44. Said lever is fulerumedv at 45 on said bearing 42.

A spring 4G on a fixedV arm 47 urges said lever toward its clutch opening position, so

Y 44 is swung to the left the toggle is set past its neutral point `and holds the clutch closed until the lever is swung back sufficiently to reverse the toggle.v

Normally the lever is free to be swung manually, but automatic restoring means are provided in the form of wheel 50 keyedto shaft 35. Said wheel has a short cam flange 51 so disposed as to wedgingly bear against and swing the lever 43 to its clutch releasing position as said wheel moves through a certain angle of its rotation.

Said shaft 35 has keyed thereto a bevel gear 52 for tilting the shocker cradle, and a crank wheel 53 for sliding said cradle. Said gear 52 coacts with a bevel gear 54 which is keyed to shaft 55 on which is keyed a crank wheel 56 having a crank arm 57. Said arm coacts with a link 58 the opposite end of which is pivoted to the arm 15 which tilts the cradle shaft 6a. The arm 15 is much longer than arm 57, so that arm 57 in turning 36()o causes arm 15 to turn or oscillate 'only about 90, as will be understood.

The crank wheel 53, or its equivalent arm 17 Vof Fig. 4, supports the crank pin 16 to which the cradle slide-rod 5"L is connected.

The operation is substantially as follows: The harvester as a whole moves forward either of draft animals or a traction engine,

the various parts of the harvester mechanism being arranged or geared so as to receive their power from the tractive source, for instance the tread wheel. By means of manual control means such as are well understood in the art, the attendant or driver regulates the operation of the harvester parts and especially the operation of the shocker, as shown in Figs. 7 and 8. To this end the operator observes visually when the cradle 1 is full, and then grasps the handle 44 of lever 43 and swings it to close the clutch 33-34, being to the left in Figs. 7

' and 8, past the retreating edge of cam flange 51 of wheel. 50. n

This causes rota-tion of shaft 35 which in turn tilts the cradle and slides it rearward and back. Just as they rotation of shaft 35v is nearly completed, the cam 51 restores lever 43 and opens the clutch, setting the plate 34 rigidly against stop 49. The cam 51 passes the lever 43 just before the toggle 37 38 snaps over, so that the device is ready p position.

for manual resetting at will. lIt will be noted that in throwing the dump mechanism into gear, the hand lever and link 26 serve to set the shock holder 26 in its effective As will be apparent, the cradle virtually stands still for -a moment at its rearmost upright position in dumping, and then rushes-forwardto its normal position-as it 'swings back to horizontal position. As the cradle slides back, therear wall or door 3 slides past wall 2 and permits the cradle to advance, leaving they sheaves standing on the ground.k 1 Y f Although but one specific embodiment of this invention has been herein shown and illustrated, it will be understood that numerlous details of the construction-shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims. y VI claim: y f
